WILLIAM G. ennn, OF SYRACUSE, new YORK.

KEY-FASTENER.

SPECIFICATION forming part of Letters Patent No. 347,170, dated August10,1886.

Application filed December 30, 1885. Serial No. 187,113. (No model.)

TO all whom it may concern:

Be it known that I, WILLIAM C. GERE, of Syracuse, in the county ofOnondaga, in the {State of New York, have invented new and usefulImprovements in Key-Fasteners, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

The object of this invention is to prevent a key from being turned inthe look from the side of thedoor opposite to that at which the key isinserted, and thereby guard against burglarious opening of the door; andthe invention consists, essentially, in the combination, with a key, ofone or more guard-arms connected to the shank of the key, movablelaterally therefrom, and an 'escutcheon provided with seats for thereception of said arms to hold the same, and thus prevent the key fromturning, as hereinafter more fully described, and set'forth in theclaims.

In the annexed drawings, Figure I is a transverse section of anescutcheon, with the key locked thereon to prevent. it from turning.Fig. II is-a face viewof the same. Fig. III is a detached side viewofthe key in its folded condition, and Fig. IV is an edge View of thelatter. c

Similar letters of reference indicate corresponding parts.

A represents the shank of a door-key, which shank may be either round,flat, or any other ordinary form, though I prefer to make it fiat for atleast part way the length thereof from the outer end back, for thepurpose of folding more compactly thereon the guard-arms a a, one ormore of which I pivot on the shank A, so as to swing laterally oratright angles therefrom, as represented by full lines in Figs. I and IIof the drawings, or into line with the shank, either outward from theend thereof, to

serve as a handle for turning the key, as shown by dotted lines in Fig.I of the drawings, or back against the sides of the shank, as shown inFigs. III and IV of the drawings, to render the key more compact andconvenient for car'- rying in the pocket. On the free ends of the armsaa, I pivot lugsb b, which can be turned back at right angles from thearms, to engage notches or depressed seats at a in the face of theescutcheon O, as represented in Fig. I of the drawings. Said escutcheon,being firmly secured to the door in any of the usual and well-knownmanners, serves to prevent the key from turning when the aforesaid lugsb b are in engagement with the notches a n.

I do not limit myself to the pivoting of the lugs 12 b on the arms a a,as it is obvious that said lugs may be rigidly attached to the arms andstill engage with the notches n n. I merely prefer to pivot said lugsforthe purpose of allowing the key to fold more compactly. Furthermore,said lugs b b may be entirely dispensed with and the ends of the arms aa swung back far enough to engage the notches or seats of theescutcheon.

What I claim as my invention is 1. The combination, with a key havingone or more guard-arms connected to the shank thereof, and movablelaterally therefrom, of an escutcheon provided with seats for thereception of said arms to hold the same, and thus prevent the key fromturning, substantially as set forth.

2. A key having the arms a a pivoted on the shank thereof to swing atright angles therefrom, and the lugs b b pivoted to said arms, incombination with the escutcheon 0, provided with notches a n,substantially as and for the purpose set forth.

In testimony whereof I havehereunto signed my name and affixed my seal,in the presence of two attesting witnesses, at Syracuse, in the countyof Onondaga, in the State of New York, this 28th day of December, 1885,

WILLIAM G. ones. [1 s.]
